Do you have an issue with paying your invoice via the Outlook-app on your IOS?
This is because Outlook has made an update where they have implemented a "in-app browser".
The browser has a problem with opening up Mobile BankID and therefor it's not possible to make the payment.
Follow these instruction:
1. Open the Outlook app
2. Go to your profile picture in the top left corner
3. Go to the cogwheel in the left corner
3. Scroll down in your settings and turn on ”Use standard browser”.
